What is the luminosity of Sadalmelik?

3,000 L☉
Alpha Aquarii/Luminosity
At a distance of 760 light years, we calculate Sadalmelik to have a luminosity 3000 times that of the Sun, rendering it about 60 times the solar diameter, large, but nowhere near as large as the truly great supergiants that would fill the orbit of Jupiter.

How did Aquarius get its name?

Aquarius was recorded in the second century by the Greek astronomer Ptolemy. Its name means “cup bearer” or “water bearer” in Latin.

What is the brightest star in Aquarius?

beta Aquarii
The brightest star in the Aquarius constellation is a rare yellow supergiant known as beta Aquarii, also known as Sadalsuud. It is 600 light-years away and has a magnitude of 2.9, which is low. Alpha Aquarii, or Sadalmelik, is a giant star located 760 light-years from Earth and has a magnitude of 2.95.

What are the physical characteristics of the star Vega?

Physical characteristics. Vega’s spectral class is A0V, making it a blue-tinged white main sequence star that is fusing hydrogen to helium in its core. Since more massive stars use their fusion fuel more quickly than smaller ones, Vega’s main-sequence lifetime is roughly one billion years, a tenth of the Sun’s.

What is the meaning of Sadalmelik?

It bore the traditional name Sadalmelik, which derived from an Arabic expression سعد الملك ( sa‘d al-malik ), meaning “Luck of the king”. The name Rucbah had also been applied to this star; though it shared that name with Delta Cassiopeiae. It is only one of two stars with ancient proper names to lie within a degree of the celestial equator.

Why is Vega used as a baseline for absolute photometric brightness scales?

To standardize the magnitude scale, astronomers chose Vega to represent magnitude zero at all wavelengths. Thus, for many years, Vega was used as a baseline for the calibration of absolute photometric brightness scales.

What is the rotation velocity of the Vega constellation?

The pole of Vega—its axis of rotation—is inclined no more than five degrees from the line-of-sight to the Earth. At the high end of estimates for the rotation velocity for Vega is 236.2 ± 3.7 km/s along the equator, much higher than the observed (i.e. projected) rotational velocity because Vega is seen almost pole-on.
